摘要 The present invention is a multidisk shell and wad for use in a multidisk shell. The wad consists of a wad base, a cushioning section attached at a first end to a top section of the wad base, and at least three alignment arms attached to a second end of the cushioning section. The cushioning section is interposed between the projectile mass and the wad base. The preferred cushioning section comprises a hollow outer cylinder and at least one inner cylinder of polymeric plastic material. Thus, there are at least two concentric cylinders providing the cushioning between the disks and the expanding propellant charge. These at least two concentric cylinders and are attached at first ends to the top side of the wad base. The wad has at least three spatially separated alignment arms having proximal ends and distal ends for maintaining the alignment of projectiles as they travel through the gun barrel. The maintenance of projectile alignment is helpful in reducing the scatter of the projectiles after they exit the gun. The at least three alignment arms are typically attached at the proximal ends to a second end of the cushioning section. The geometry of the at least three alignment arms is useful in the maintenance of the alignment of the projectile under acceleration. A preferred embodiment is a totally symmetrical configuration. Thus when the wad contains three alignment arms the arms are spaced at regular intervals of 120 degrees; four alignment arms are separated by 90 degrees; etc.
权利要求

What is claimed is:1. A wad structure comprisinga. a wad base;b. a cushioning section with an outer diameter attached to the wad base; andc. at least three spatially separated alignment arms attached to the cushioning section, said alignment arms having a significant spacing between each arm,wherein the wad base further comprises a powder cup and a burn through plug placed in the powder cup.2. The wad structure of claim 1 wherein the wad base has an outer diameter greater than the outer diameter of the cushioning section.3. The wad structure of claim 2 wherein the cushioning section further comprises:c. at least two axially aligned hollow cylinders, an inner cylinder and an outer cylinder, attached to the wad base at proximate ends; andd. at least one alignment segment connecting the outer cylinder of the at least two axially aligned cylinders to the inner cylinder of the at least two axially aligned hollow cylinders.4. The wad structure of claim 3 wherein the at least three alignment arms are attached at proximal ends of the alignment arms to a distal end of the outer cylinder of the cushioning section.5. The wad structure of claim 1 wherein the cushioning section further comprises:a. at least two axially aligned hollow cylinders, an inner cylinder and an outer cylinder, attached to the wad base at proximate ends; andb. at least one alignment segment connecting the outer cylinder of the at least two axially aligned cylinders to the inner cylinder of the at least two axially aligned hollow cylinders.6. The wad structure of claim 5 wherein the at least three alignment arms are attached at proximal ends of the alignment arms to a distal end of the outer cylinder of the cushioning section.7. The wad structure of claim 6 wherein an inner surface of the outer cylinder is canted relative to an outer surface of the inner cylinder.8. The wad structure of claim 1 further comprising at least three longitudinal ribs attached to the outer diameter of the cushioning section, at least one of said ribs is further placed along the outer sides of each of the alignment arms.9. The wad structure of claim 1 whereinb. a cushioning section attached to the wad base comprised ofi. at least two axially aligned hollow cylinders, an inner cylinder and an outer cylinder, attached to the wad base at proximal ends; andii. at least one alignment segment connecting the outer cylinder of the at least two axially aligned hollow cylinders to the inner cylinder of the at least two axially aligned hollow cylinders;c. said at least three alignment arms attached at proximal ends of the aliginment arms to a distal end of the outer cylinder of the cushioning section; andd. at least three longitudinal ribs attached to the outer diameter of the cushioning section, at least one of said ribs is further placed along the outer sides of each of the alignment arms.10. The wad structure of claim 1 wherein the cushioning section further comprises an outer cylinder and an inner cylinder, and said at least three alignment arms attached at proximal ends of the alignment arms to a distal end of the outer cylinder of the cushioning section, three attachment sections connecting the outer cylinder to the inner cylinder and spaced at approximately 120 degree intervals, the alignment arms are also spaced equally about the cushioning section at approximately 120 degree intervals, and three longitudinal ribs attached to the outer diameter of the cushioning section, at least one of said ribs is further placed along the outer sides of each of the alignment arms.11. The wad structure of claim 1 wherein the cushioning section further comprises an outer cylinder and an inner cylinder, and there are four alignment arms attached at proximal ends of the alignment arms to a distal end of the outer cylinder of the cushioning section, four attachment sections connecting the outer cylinder to the inner cylinder and spaced at approximately 90 degree intervals, the alignment arms are also spaced equally about the cushioning section at approximately 90 degree intervals, and four longitudinal ribs attached to the outer diameter of the cushioning section, at least one of said ribs is further placed along the outer sides of each of the alignment arms.12. A wad structure comprisinga. a wad base comprises a powder cup and a burn through plug placed in the powder cup;b. a cushioning section with an outer diameter attached to the wad base; andc. a net structure attached to the cushioning section, said net structure adapted to receive a plurality of projectiles and cushion said plurality of projectiles as said plurality of projectiles travel the length of a gun barrel.
